Dealing with UTF-8 text using the PHP mail()-function

On one of my PHP-based websites, users can send mails via a simple text form. I had a problem with special characters in the subject or message body. The webpage has a <meta charset=”utf-8″ />-tag, which causes problems when people enter special characters, like é or € or “smart quotes”. They get sent via the mail()-function and show up like Ã³ or Ã© or â€™.

Deep down in the user comments in the documentation on the mail()-function, I found a small function that solved this easily:

Just use mail_utf8() instead of mail() on a UTF-8 page and a proper UTF-8 mail will be sent out.
